Switch at end of June sits on 4.7m units, Zelda BotW and MK8D in same period at 3.92m and 3.54m, that puts 83% and 75% attach rate, thats crazy. :)
Also its worth mentione that every 1st party title Nintendo (except their digital only titles) has put on the Nintendo Switch has been a 1 million seller as of June.
Those of you good at math will have already worked out that Zelda has an 83% attach rate and Mario Kart 8 Deluxe has a 75% attach rate.
